I have never seen a 6.8SPC AR and I have spent a lot of time at the range.
224V is still alive but 6ARC is giving it a run for it's money. |

Quoted: The most experience with 6.8SPC I have was getting several Boxes from an Estate and for a while it was a thing, but it and .224 Valkyrie (and some other I expect) have fallen by the wayside or have they? Is anyone offering 6.8 complete uppers or is it a specialty? (read "expensive") Lots of people offer uppers. I do think it's a fringe cartridge as it's only used in the ar. I think it's likely it and the Valkyrie eventually fall off. Kind of think the grendel might as well. It has a bit of advantage in that there are 3 or 4 bolts that are sold in the caliber. But I kinda think that the 6mm arc eventually becomes the main caliber outside of 5.56. the arc is actually being used in the military and I think Willis start getting more use. That typically means it will become more popular |

It's an awesome caliber for the AR-15 platform. Lot of firepower for the platform and still very controllable. However the ammo is expensive and harder to find. For hunting it's either my smaller and lighter AR15 in 6.8, or my bigger and heavier AR10 in 308. Ammo costs about the same. But 308 is easier to find. Of course follow up shots are easier with the 6.8 SPC.

It's not dead. Winchester has come out with a new factory loading very recently. To get the most out of the 6.8, you really need to handload.
I have 3 6.8's. A few coworkers have rifles. I've used mine for deer hunting the last 5 or 6 years. I worked at Barrett when we first started that project. We worked with 5th Group at Ft Campbell a lot with it. I buy brass and projectiles when I find them at a good (for me) price. |

Not dead, it’s just become a hunting caliber with a dedicated fan base… so niche in other words. It’s great when hand loaded. I shot a bull elk with my SBR 6.8 this last year.

That's my take at least - am I missing something? |

Quote HistoryQuoted: You think grendel is more common than 6.8 and 7.62x39? I really don't know. I have a bunch of uppers in various calibers but don't shoot anything but 5.56. The only non 5.56 ARs I have seen are 7.62x39, 500 beowulf and 450 bushmaster Quote HistoryQuoted: Quoted: No, not dead. In small frame AR, current usage ranking it seems to me 223/5.56 300 BO 6.5 Grendel 6.8 SpC .224 Valk 7.62x39 6mm Grendel.. er (ARC) Oh definatly. Just by brass alone, you will see 5 Grendel casing for every 6.8, if not more. And 5 300 bo casting for every Grendel. And like 50 5.56 for every 300 BO. And range encounters observation matches that trend. For field hunting I think that flattens out more, 6.8 is quit expensive to shoot, so those who run it, tend to be more focused field hunters, so it is underrepresented at the range and by brass count alone. 6.8 is arguably slighter better at sub 300 yard field hunting than Grendel, but not by much. It's a good round all the same - it just tends to cost more, and no common source brass to repurpose for a reloader in a pinch (Grendel reloaders can run 7.62x39 brass). And legs aren't quite as long for the distance gong range. To be honest, 25 cent Wolf Steel Grendel ammo availability made it a no-brainer on which to pick between the two, and heck, that made even having a 5.56 AR kind of optional. But alas, that door is perminantly closed- so ammo cost differential for Grendel is kind of gone. 6.5 Grendel is still IMHO the best overall general purpose civilian small frame AR round for reasons mentioned, but 6.8 is very close, trading range for a little better terminal performance at essentially all pragmatic hunting ranges. It's just the net increase in that performance IMHO is considerable smaller than the net loss of distance range compared to Grendel. If your world and interests never ever but ever will exceed 300 yards - 6.8 is an excellent choice that even as a Grendel snob, I can't besmirch. 6mm ARC to me however, is to me a waste of good Grendel brass, as the higher P rated .224 Valk is already there. But it's OK to like stuff I don't.

I don't own AR's in any other caliber, so it's not dead to me. If ammo prices ever got down to around $0.60 a round I'd buy a 1k round case of 110gr. right now.

If so, the 6.8 is the next 5.56 so far as ammo/components are concerned. |

I have a 6.5 Grendel and like the round, even the Wolf stuff is pretty good, and having other 6.5 Rifles doesn't hurt either. (6.5x55, 6.5CM)
How does the 6.8 do with slightly heavier bullets such as 130~150 grain weight? I like the idea of the 6.8 in having other Rifles using .277 Bullets, but I don't want to tie up in another caliber just to see it go the way of the .30 Remington AR or other flash in the pan cartridges. |

Nor is that fitting on a small frame AR15 frame. With regards to the 6.8x51/ .227 fury, we already had the heavy high-recoil hard-hitting larger power conversation. It was called the M14 and is a terrible choice for general issue line troops, but good choice for DMR. |

It's not dead but it definitely lost the caliber wars to the 6.5 Grendel.
The 6.8spc is a very good hunting caliber and will be around for a long time I imagine. It's just not nearly as popular as it was. Since you already have a 6.5 Grendel there's no reason to get a 6.8spc because you're not gaining anything. Unless you just want one and then why not? |

I've always had an interest in 6.8 but in the ~20 years of it being around, I've never purchased anything in it or for it. I do wish I would have bought one of the ACR 6.8 conversion kits when Bushmaster blew them out before the big bankruptcy.
They screwed up pretty big with the early chamber issues so there was always an air of uncertainty around "is that safe to shoot" for folks that didn't really know the SPC-II or other chamber variants that fixed it. It's a niche round now. I'd rather buy a 6.8 than a .300 though.

Quote HistoryQuoted: if you are looking to kill something with an AR get a 6.8 This is where I warmed up to it. For years I stayed away from boutique class cartridges. In a moment of weakness I decided to build an upper, wanted to use what lowers I already had, so just a push pin conversion. Flat top upper, a he who may not be mentioned lightweight 18” barrel, his super bolt. No a tactical timmy rig for me, just an upper that I might use to shoot a deer with. The caliber is just right for any 300-350 yard max set up I may hunt. Barnes 95 grain TTSX are what I chose to load in it. No meat yet although I did carry it a few times last season. |

And pragmantically is the same number for any individual hunt. It would be interesting to see if someone would do same with 6 ARC. My own expectation is same hunter/conditions that goes down to the 60s/100 hogs, because little diameter fast bullets rely on bullet design, and idealized impact path. Otherwise the either ice-pick, or explode at the surface, IMHO. But I can change my mind on things if I'm shown to be in error. |

I've been extremely happy with my 6.8 on whitetails (suppressed Wilson 11.3", Hornady 120gr SST); a buddy uses his on deer and hogs and it's become his main rifle as well. I wish the ammo was more common and cheaper, if I were buying new today I'd get 6.5 just because of availability.

My favorite spin-off from the 6.8 is the 25x68. I think if it was marketed as a dual purpose hunting cartridge vs long range round, it would have appeal. Out of an 18” barrel it literally mimics 250 savage, which is a classic hunting round.
It’s one of my favorite cartridges in general, but these days with young ones, time on the reloading bench is getting fewer and further between so I’ve been thinking about selling the components, but it’s hard to… I haven’t killed anything with it yet, but have developed some nice loads. My favorite so far intended for predator/javelina is a 85gr Ballistic Tip at 3k fps. |

I don’t see it as dead, just retired.
It didn’t make the stardom hoped, in the form of common military use. Sure some specops might use it, but that can be said of most any quality gear. It would need to be issued to normal troops for it to actually see the popularity. It seems to be a plenty capable hunting cartridge, and that’s what keeps it alive. If it wasn’t an AR platform, I don’t think it would even be known in the hunting world. Easy enough to just go buy a more mainstream, 2.800” length cartridge with way more ponies under the hood. I think it’s cool that it did actually find success for harvesting game. It is great that so many effectively use it, keeping it going as proof that the AR is such a versatile platform. |

Eventually we'd maybe see a 6mm variant just like happened with the Creedmoor and Grendel. You get really into dreamland and you also end up with a 30 variant like the HRT standardized. |

Both are comfortably in a niche category for the AR15 and more than likely will remain there, the same as 458 SOCOM, 300 HAMR and a multitude of others. |

Quote HistoryQuoted: Wasn’t the Army doing some kind of trial with 6.8 something? 6.8x51 has been adopted. The civilian equivalent is .277 Fury. |

Quote HistoryQuoted: Wasn’t the Army doing some kind of trial with 6.8 something? In the early days of Iraq and Afghanistan there were (IMHO) multiple attempts at getting the Military to field, adopt or test "new and improved" system, ammunition, and combat driven equipment. The 6.8 Remington was born out of this, along with the Remington ACR (and some forgotten others) https://en.wikipedia.org/wiki/6.8mm_Remington_SPC At one time, a Remington Employee signed out a couple of these Rifles and ammunition for use at a local Range where a bunch of arfcommers gathered for an evening feast and entire Range day the following Morning.....good times! |

And .308 won't fit in Fury (neck area won't chamber). The only cartridge to fuck this concept up of relevance is .300 BO. And just like that, first question after a .223 kaboom is no longer "do you reload?", but is now "do you own a .300 BO?" |

Only with super light/narrow ogive bullets or almost zero neck tension/crimp. |

Wonder how expensive it is to manufacture those cases, and how long the barrels last… |
